The term stepping is associated with
1) Root canal preparation
2) Direct gold condensation
3) Silver amalgam condensation
4) Fracture mandible

Conservative Dentistry Answer: 2

The main aim of cavity preparation
1) To prevent the caries
2) To prevent plaque accumulation
3) To treat the caries
4) To reduce the pain

Conservative Dentistry Answer: 3

Crazing, cracking and wear fractures of the composites is due to
1) Low modulus of resiliency
2) High modulus of elasticity
3) Low surface hardness
4) Low setting shrinkage

Conservative Dentistry Answer: 1

The method of proper condensation of gold
1. Concentrated overlapping from centre towards periphery of the cavity
2. Concentrated circles overlapping from periphery towards the centres
3. Both of the above
4. None of the above

Conservative Dentistry Answer: 2

For class II amalgam preparation, axiopulpal line angle is
1. Bevelled acute angles
2. Bevelled obtuse angles
3. Right angles
4. Rounded

Conservative Dentistry Answer: 4

In modified class III cavity restoration, retention is obtained mainly by
1) Acid etching
2) Retentive groove/slot
3) Retentive point
4) Retentive pin
